Supreme Court Term Limits and Regular Appointments Act of 2023

This bill would require Supreme Court justices to retire after 18 years of service (except for those appointed before the law's enactment), and mandate that the President nominate one justice during the first and third years after each presidential election. It would create a "Senior Justice" category for retired justices who can temporarily fill vacancies until new appointments are confirmed. The Senate would be required to act on nominations within 120 days, or the nominee would be seated automatically. The law directly affects future justices and the appointment process, while exempting current justices from the retirement requirement.
